WINDING DEVICE `EoR sTAroRs AND ARMATURES or MOTORS.

Application ledNovember 18, 1920. Serial No. 425,023.

To @ZZ 'wlw/m it may concern Be it known that we, HENRY KLEIBER and. FRED MEHR, citizens of the United States of America, residing at Teaneck, in the county of Bergen and State of New Jersey, have invented new and useful Improvements in 'lVinding Devices for Sta tors and Armatures of Motors, of which the following is a speciication.

The object of the invention is to provide simple and relatively inexpensive and eilicientL means for facilitating the winding or application of coils to the stators of alternating current motors, the armatures of direct current motors either in repair or shop work or otherwise and in analogous operations requiringthe accurate positioning of winding or coils with reference to either rings or cones; and with this object in View the invention consists in a construction and combination of parts of which preferred embodiments are illustrated in the accompanying drawings, wherein Figure 1 is a side view of an apparatus embodying the invention showing the sameapplied to the coil or winding of a stator.

Figure 2 is a front view of the same.

Figure 3 is a sectional view on the plane indicated by the line 3-3 of Figure 1.

`l3`igure 4; is a sectionalview of the foot forming the fibre holder.

Figures 5 and G are Views of a slightly modified construction ofthe apparatus applied respectively to the operation of winding a stator and an armature.

The apparatus consists essentially of a bearing headl and a foot 11 one of which 'ries a feed screw l2 for engagement by l Ynut 13 connected with the other, suitable meansbeing employed .in connection with the feed nut for actuating the same to cause a separationof the head and foot, or an extension of the apparatus under YVsuch conditions as to force the winding or coil 14- into the seats 15 of the stator or armature to be wound.

In the construction illustrated in Figures l to 4; inclusive the head 10 is exteriorly converged to bearagainst the inner perimeter of the stator shown at 16, said head preferably having a sleeve lOfL detachably fitted upon the stem 17 forming alterminal ofthe feed screw and secured in place by means of a pin 18 to the endthat the head may be interchanged 'with others having a different curvature of exterior surface to suit the diameterof the stator which is to bewound. rlhe foot similarly is provided with a stem 1la removably fitted in a socket 19 in a stem 20and secured in place by a pin 2l to provide for the interchanging of the foot which consists essentially of a cross head 22 provided with a seat 23 for the reception of the fibre bar 24 for contact withthe coil or winding and serving upon the extension of the apparatus or the separation of the bearing head and the foot to force the coil into the seats of the stator.

In the construction illustrated the feed nut 13 is provided with a toothed periphery forming a bevel gear with which meshes a bevel operating gear 25 having its spindle 26 provided. with a terminal crank 27 by means of which a relatively quick extension of the shank of the tool represented jointly by the feed screw 12 and the tubular stem 20 may be made to bring the head and foot into operative relation respectively with the diametrically opposite portions of the inner periphery of the stator in which a winding is to be seated.

Also carried by the spindle or shaft of the operating' gear 25 is a ratchet head 28 for engagement by a pawl 29 having an actuating spring 30 and mounted upon an operating lever 31 to the end that by the oscillatory movement of the lever a slow and for example rotary movement may be eommui nicated to the operating gear 25 and hence to the feed nut to exert the necessary pres sure to force the coil into the seats of the stator. The pawl 29 is provided with a terminal pin 32 by which it may be withdrawn from engagement with the ratchet teeth when it is desired to quickly set the terminal head and foot elements of the apparatus.

In the modified construction indicated in Figure 5 the head is provided with a stem 34 swiveled as at in a feed nut 86 which is engaged with a screw threaded portion 37 of a stem 88 which carries the foot 89, said feed nut being in the form of a sleeve and having radial arms i-O whereby through the retention of the nut the shank represented jointly by the stems 34 and 3S may be extended to separate the head and foot members and 39 to force the coil 41 into the seats 4t2 of the stator 4:3.

In, the form of the invention illustrated in Figure 6 which is applicable more particularly to armatures of the D` C. motors, the extensible shank is :represented by the stems 44 and 45 respectively carrying a bearing head 46 and foot 47, and said shank being extensible by means of a feednut 48 which is engaged With a threaded portion of the stem 44, a strap 49 being arranged vin embracing relation With the core or armature 50 to form a bearing for the head 4G, i

lt will be understood that in the use of either' of the terms ot coil settiilgy or Winding aplniratus en'ibodying the invention the l'orcible seating oi the coil under conditions tending to insure accuracy may-be cli'ected with ample opportunity :for the olfierator to` observe the progress ot the Work by reason of the fact that the operating means 'lor ef-, eeting the extension olf the shank or 'the relative separation oi the foot and head elements thereof may be actuated slowly and at the same time With the minimum of effort on the part of the operatorrand it Will further be obvious that the seating of the coil by means of a steady and slow pressure due to the relative movements of the head and foot elements of the apparatus can be accomplished with less risk oi' injury to the winding or the insulation thereof` than is possible when as in the ordinary practice the operation is accomplished by the aid ot a hammer or like tool lor impelling va bit or punch.

In particular let it be noted with referl ence tothe forms of apparatus illustrated.

in Figures l to 4 inclusive that having once set the head and ioot elements by means o't the crank 27 through the diameter of the stator, the alternate extension and contraction of the shank necessary to force the coil into the seats oi the ring may be effected by an oscillatory or vibratory movement of the operating lever 31, the tool being shifted 4 terminali-head vand foot elements7 and means lor effecting an extension and contraction of the shank, the head and l'oot elements being Ainter-changeably connected with the membersl of said shank.`

2. A Icoil settingor wmdiug apparatus having anl extensible `shank provided With i terininalfhead and foot elements, and means i'or ejliectmg an extension and contraction ol". theshank, the foot member consisting of curved cross head forming a fibre holder.

A coil setting or winding apparatus -having an extensible shank provided yvvith.

terminal head and foot elements, and means tor effecting extension and contraction of the shank, the lhead element having a convexed upper tace for bearing engagement with the inner. periphery of a stator and the toot element being provided with means for engaging a coil to force the latter into the stator slots.` i

4. A coil settingor winding apparatus hav/*ing an extensible shankprovided with terminal head and foot elements, and means 'for' effecting extension and contraction of the same, in combination Witlra flexible member for disposition in embracing relationwith an armature core, said flexible member constituting a bearing for said head element.
